Description

Hacker Public Radio is an podcast that releases shows every weekday Monday through Friday. Our shows are produced by the community (you) and can be on any topic that are of interest to hackers and hobbyists.

Diffie-Hellman Key Exchange is based on work initially done by Ralph Merkle, and remains one of the key developments in secure communication over the Internet. In this episode I try to explain just how this works, with an example of a calculated key exchange.

Thaj: Voice fading fast. Need a boost. With a little lemon and some local honey http://www.traditionalmedicinals.com/products/throat-coat/
x1101: Harpoon IPA - http://www.harpoonbrewery.com/beer/1/harpoon-ipa
pokey: "my beer is a knife" Smuttynose Robust Porter https://smuttynose.com/beer/robust-porter/. I sharpen it with a Spyderco Triangle Sharpmaker https://www.spyderco.com/catalog/details.php?product=77. It is awesome.
FiftyOneFifty: Junior Johnson's Midnight Moonshine
THINGS WE TALKED ABOUT
We discuss the upsides and downsides of affinity groups. Pokey wonders why terminology for simple things are changed in sci-fi stories. How exactly do population and economics work together?

OUR AUDIO
This episode was processed using Audacity http://audacity.sourceforge.net. We've been making small adjustments to our audio mix each month in order to get the best possible sound. It has been especially challenging getting all of our voices relatively level, because everyone has their own unique setup. Mumble is great for bringing us all together, and for recording, but it's not good at making everyone's voice the same volume. We're pretty happy with the way this month's show turned out, so we'd like to share our editing process and settings with you and our future selves (who, of course, will have forgotten all this by then).
Mumble uses a sample rate of 48kHz, but HPR requires a sample

Lostnbronx considers the effect that Elon Musk and SpaceX are having on the latest push for the exploitation and exploration of space, and the danger of pegging the future of the human race upon the showmanship of one man.

CleanHPR2507: Racket, Nix, Fractalide and the sounds of a Hong Kong New Town

Listen to me walk through five shopping malls and one bicycle tunnel, as I rant about how flow-based programming microservices and functional package management will save the future of programming and software reuse, and usher in a new era of software quality and productivity!
If it sounds like I'm a bit down about working alone on racket2nix, you're interpreting me wrong! I didn't expect any feedback at all from the small to non-existent racket/nix intersection, but it turns out the intersection is larger than I thought, and I'm grateful for any words of encouragement, and feedback in any form on what the community needs.

How I Got Into Podcasting
The Background
Audio production has always been an interest of mine: my late grandfather was an audiophile, my dad ran an AV studio in Woking (the one where the Spice Girls were formed - my dad got mentioned in a couple of their autobiographies) and now runs his own AV consultancy business, and my cousin also runs an AV consultancy... so there’s a definite family history in there.
I dabbled briefly with hospital radio (as a technician, rather than a presenter) in the late 80’s, and I was a technician and presenter on College Radio in the early 90’s where I hosted a show called “The Barry Manilow Fan Club” on Friday lunchtimes.
Yes, I am a huge fan of Barry Manilow - he’s given me a lot of inspiration as a musician - no, I didn’t play any Barry on the College Radio show.
I’d also had a few people say that I had a good radio voice. Others say a good radio face, but I don’t like them anymore.
The Catalyst
In 2007, I discovered this podcasting lark through a couple of friends who had their own podcasts. One was The Random Three: a personal musical journey where Mark - the host - would play three seemingly-random pieces of music from his own collection (thus, not podsafe) and explain the reasons why he chose them. Most of the time, these seemingly-random tracks actually had a theme, but it didn’t necessarily become apparent until after the second track. It was a great show - now sadly defunct - and I really miss it. I even submitted my own music choices for Mark to present.
The other was Dumbed Down Life: three chaps nattering about “stuff” and playing some music along with it. Another great show, which - although it still exists - currently releases episodes every year or so.
What drew me to these shows - apart from being friends, was the fact that these were regular guys, not professionals.
That led me to think “I can do that”, so I set about proving - to myself, mostly - that I could.
The Start
One Thursday in early March 2008, when the wife had gone to the gym for a couple of hours, I grabbed my Logitech headset, my Linux laptop, a handful of tracks from the Podsafe Music Network, and a piece of software called IDJC, and recorded the first ever episode of The Bugcast. It was just over 22 minutes long, and it was dire. Utterly dire. Every so often, I go back to it and listen and cringe and marvel at how much better the show is now!
The music back then wasn’t strictly podsafe either: the first track I played was Moloko’s Sing It Back… but I didn’t worry about it then, as I got the track from a source that gave implicit permission for use in podcasts.
I did do a show - episode 20 - which was a nostalgic trip back to my college years, where I played tracks by Chad Jackson, Japan, and Dream Warriors. This was a complete and intentional violation of copyright on my part, which led me to pull the show only a few weeks later. I did rerelease the show two years after that, but with the offending tracks removed. However, there is a story to the show, so I would recommend you go listen.
Back then, it was just me and a small listener-base of friends, their family, their families’ servants; their families’ servants’ tennis partners, and some chap I bumped into in the mess the other day called Bernard. But as time went on and I got more experience, I was really enjoying what I was doing, and

Lostnbronx measures how loud his own thoughts are -- or rather, how loud outside noise has to be before they are disrupted.
It turns out that unwanted music in his ears at -30 dB is when his train of thought starts to derail.

Fun Show!!

A great community based show, each day brings a different host and a different subject!

Informative

by

This podcast is very informative, but don't expect to become certified in any of the subjects featured. It is volunteer supported radio show, so it doesn't go too in depth. Also, if you think you know about a relevant subject, put together a podcast and submit it to HPR!
